Drill Rod rounds are tough, free machining general purpose tool steels. They are used for punches, tools and dies, drills, taps, arbors, roller bearings, dowel pins and a variety of machine parts where high strength and long life are required.

Drill Rod rounds are annealed and ground and polished to a surface finish better than 30 microinches. The excellent finish, strength and machinability makes drill rod ideally suited for power drive shafts and applications where accuracy and straightness are required.

Drill Rod rounds are available from stock in 3 foot lengths in a wide range of diameters, in Water Hardening (W-1), Oil Hardening (O-1), Air Hardening (A-2 & D-2), High Speed Steel (M-2) and Shock Proof Air Hardening (S-7) grades and Hot Work Air Hardening (H-13) available Annealed and Pre-Hardened.


H-13 HOT WORK PRE-HARDENED
Designed for hot work applications, this free machining grade is pre-hardened to the Rc 42-46 range and still retains good machinability properties. Since it is furnished pre-hardened, all problems of size change during heat treatment are eliminated and work can be directly machined to finished dimensions. H-13 pre-hardened often is used as a high strength machinery part.
